Scoring
How to set up scoring in Colibri
Scoring is a step interaction in Colibri that allows participants to be scored when answering questions in a self-paced exercise. This helps to reinforce correct behaviour in participants through consequence.
There are three different options when it comes to scoring:
Set
Set the participant's total score
Increment (this is the default option)
Add an amount to the participant's accumulative score over an exercise.
Decrement
Subtract an amount from the participant's accumulative score over an exercise.
How to
You can configure scoring in the Editor via the Interactions tab in a step:

1. Set
Set the participants total score
At the beginning of an exercise or if you want to reset the participant's score. Set the score to 0 (assuming the score should start at 0)
You might also want to award a specific value at any time and branch on this later

If you are using the Set option to reset the participant's score, pair it with the Erase all action to delete all previous messages and, effectively, reset the exercise.
2. Increment
This is the default option because it's the most likely scoring option you'll want to use.
Add an amount to the participant's accumulative score over an exercise
If set to 0, nothing will be added
When using questions, configure all incorrect answers' scoring value to 0, but the correct answer's scoring value to 1 (or more if you like)

3. Decrement
Subtract an amount from the participant's accumulative score over an exercise
If set to 0, nothing will be subtracted
If you'd like to take points away from a participant for getting a question wrong
